The College of American Pathologists (CAP) announces the expansion of its current Sample Exchange Registry for Alternative Assessment.

This service now includes all clinical laboratory disciplines. The Sample Exchange Registry is an Internet-based service designed to connect laboratories performing testing where no formal proficiency testing (PT) is available.

Laboratories can participate in the registry service at any time. When at least three laboratories are identified as testing for the same analyte, the CAP will facilitate the sample exchange. Access the Contact Information Form.

If your laboratory can provide materials for the exchanges in which you participate, please contact CAP at the address listed below for shipping details.

The Material Submission Form(PDF, 120 KB) can be used to provide the sample information. Upon receipt of the material, the College will distribute the samples to participating laboratories testing for the same analyte. The laboratories will test the samples and send their results to CAP. The data will be anonymized and each individual laboratory will receive its own results along with an anonymous summary report of all the participants.
